Answer:

La reproducción sexual indirecta no implica una interacción física entre los dos organismos de la misma especie, pero entonces, ¿cómo ocurre? Verás, este tipo de reproducción es mayormente utilizado por organismos que viven en el agua o por las plantas. Debido a que estos tienen muy poco o no nulo movimiento, estos organismos expulsan al ambiente sus células sexuales. Cuando estas células se encuentren con las células sexuales del otro género ocurre la fertilización, generando nuevos organismos. Un ejemplo claro de esto son las estrellas de mar, que viven en sustratos donde no tienen tanto movimiento, por lo que optan por expulsar sus gametos.

Reproducción asexual. Aquí no intervienen dos individuos de sexos distintos para generar un nuevo organismo como ocurre en la reproducción sexual, sino que a partir de un solo progenitor se crean uno o más seres vivos. Esto significa que un organismo se parte o se divide y que a partir de ese fragmento se genera uno o más organismos idénticos morfológicamente y que poseen la misma información genética. Este tipo de reproducción ocurre en los animales, las plantas y en microorganismos como las bacterias.

Which of the following is a correct statement about sugar movemetn in phloem?
Simora [160]

Answer:

a. movement can occur both upward and downward in the plant

Explanation:

The phloem loading causes the accumulation of sugars in the sieved elements generating a negative solute potential (quedas), with a drop in water potential (ψw), so water enters the sieved elements increasing the turgor pressure (ψp). With the discharge of phloem in the drain occurs lower concentration of sugars in the screened elements, increases the solute potential, becoming positive, thus the phloem water potential increases and thus the water leaves the conducting vessel. In the specific case of sugar movement in the phloem, it can be stated that this movement can occur both up and down in the plant.

The most valuable resource that the Indians had to trade with the Europeans?
Alina [70]

B. Deer skins.

Why? Probably because back in the days Indians used to be extremely talented when it came to hunting for food, water, and even warmth. I doubt they'd have tools to spare besides bows and most likely rock knives they've hand made to cut down the bone and other stuff to make seasonings with. Building styles? No. Why would the Europeans ask Indians to trade building techniques? I doubt it. B is definitely the answer.
